Rangers manager Dick Advocaat believes his side's victory at Kilmarnock proved how their injury problems have made it so easy for all-conquering Celtic.

The Dutchman had the rare luxury of naming an unchanged side for the first time this season and it brought them an impressive win at Rugby Park. But it seemed ironic that after Celtic had wrapped up the championship, so clinching the Double, that Advocaat would find some consistency in his selection.

Advocaat said: "You can see for yourself what can happen when I'm able to select the same players again. That is the first time this season that I've been able to name the same team and we were a different side. I congratulate them (Celtic), but I also promise them it will be a different story next season."
